Abstract

Indonesia is rich in flora diversity, very potential for the development of
natural dyes. The advantage of dyeing fabrics with natural dyes is that
they contain antioxidants and environmentally friendly. The purpose of
this study was to optimize the dyeing process on chitosan-modified
fabrics with variations in temperature and solution ratio. The dyes used
were kesumba keling seeds (Bixa Orellana) and sappan wood
(Caesalpinia sappan). The analysis carried out is the analysis of the value
of color differences (E), calculated to determine changes in color
intensity. The dyed fabrics were tested for fastness to light, heat, and
washing. The best value of E was obtained at a temperature variation
of 70 oC and a ratio of fabric weight to volume of solution 1:75 for both
dyes from kesumba keling seeds and sappan wood with each E value of
6.22 and 11.84. Supported by the test results of fastness to sunlight and
iron heat which gives good results.
